`AUTOMATIC) REVOLVING CAR-DUMP.

SPECIFICATION forming part of Letters Patent No. 790,586, dated May 23, 1905.

Application filed May 14;, 1904. Serial No. 207,960.

zen of the United States, residing at War Eagle, in thecounty of Mingo and State of West Virginia, have invented a certain new and useful Improvement in Automatic Re-` volving Oar-Dumps, of which the following is a specification.

My invention relates to apparatus for unloading cars, and has for its object to provide means for dumping an entire car-load of coal, ore, or any similar material by turning'the car completely over and allowing the con tents to fall out.

Cars and like appliances of the construction in common use are usually emptied by opening a trap in the bottom of the car and allowing the contents to fall through. `In

practice there are serious objections encountered in the use of such cars, among which are thev complicated character thereof, the height of the bottom of the car above the track necessary to accommodate the trap, the liability of accidental opening of the trap, thus spilling the contents along the track, the additional initial cost, and the necessary expense of repairs.

In my improved dumping device a coal, ore, or like car of any construction may be dumped, the dumping being accomplished by simply turning the car completely over and -allowing the contents to fall out.

With these and other objects in View my present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown, in the accompanying. drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departingfrom the spirit or sacrificing any ofv the advantages of my invention.

In the accompanying drawings, Figure I represents an end view of my improved cardump in position to receive a car for dump-V ing, the positions of the cars upon the dump,

being shown ,in the dotted lines.

Fig. 2 is a side elevation.

Fig. 3 is a vertical section 5o taken on line 3 3 of Fig. 1, and Fig. 4 is a detail View of the four-way valve used to adlstruction I mount a shaft l of sufficient strength in suitable journal-bearings 2. Upon such shaft l I mount a plurality of I-beams 3 3 by passing shaft 1 therethrough. I arrange the I-beams in a parallel series, as

shown, and secure them against rotary displacement by a key or in any other approved manner. j

A About shaft l as an axis I construct a plurality of circular members 4 4, with I-beams 3 3 as diameters. At a point approximately midway between the middle of such I-beams and their ends I erect uprights 5 5, which occupy the positions as sectors of the circular .members and at right-angles to said I-beam 3 3. rlhese uprights 5 5 serve to strengthen the structure and to serve as guides for the clamping device to be hereinafter described.

To further strengthen the structure, I em-` ploy braces 6 6, as shown.

Upon I-beams 3 3 as a platform I secure rails 7, 8, 9, and l0 parallel with shaft l, rails 7 and 8 being upon one face of the platform anderailst) and 10 upon the opposite face. Rails 7 and 9 are located nearer to shaftl than rails 8 and 10, so that the center of gravity of a car standing upon either of such pair g of rails is not directly over shaft 1, but somewhat to one side thereof.

To prevent displacement of the cars while being dumped, I provide a plurality of clamping members 11 11, consisting, preferably, of I-beams disposed transversely above each car and adapted to assume the positions indi- .cated at 11 ll and to forcibly hold each car against displacement. As a means for actuating such clamping member I preferably provide a plurality of vertically-disposed cyl- Rods 13 13, connected with such pistons, are pivotally connected with the ends of clamping members 11 11. To operate the clamps, the cylinder receives between the end nearinders 12 12 with pistons therein, as indicated.

IOO

est the clamping member and the piston any desired fluid under pressure, as air, steam, or

, water conducted to and into such cylinders through pipes 14 14.

For the purpose of preventing sidewise displacement of the car l provide a plurality of clamping members 15 15, preferably constructed of heavy wooden timbers, disposed longitudinally with and adapted to clamp the sides of a car, as indicated at 15 15. As a means for actuating such clam ing members l provide a second series of cy inders 16 16,' horizontally disposed with pistons therein and thrust-rods connecting such pistons with the clamping members 15 15. These cylinders are adapted to receive alluid under pressure at the end opposite such clamping member from pipes 14 14. The introduction of lluid under pressure from pipes 14 14 to cylinders 12 12 and 16 16, as indicated, forces clamping members 11 11 and 15 15 toward and upon the car, thus retaining the car securely in position while being turned entirely over. When the rotation of the dump has been completed and it is desired to remove the car, fluid under pressure is admitted to the opposite ends of cylinders 12 12 and 16 16 through pipes 17 17 and the first-admitted fluid allowed to exhaust. This produces an opposite movement of the pistons and causes clamping members 11 11 and 15 15 to release the car from pressure and to assume the positions shown in the drawings. To control the flow of the pressure-exerting fluid, l prefer to introduce four-way valves 18 and 19 into the system of pipes. These valves are shown in detail at Fig. 4 and are preferably so constructed and disposed that with the valve-lever 20 in the position shown in Fig.

4 the fluid admitted at 21 passes through such valve into pipes 14, causing a clamping pressure to be exerted upon members 11 11 and 15 15, and the fluid contained in the cylinders passes out through the other passage of the valve and exhausts at 22. By rotatingvalve-lever through one-quarterof a revolution to position 2Oa fluid admitted at 21 passes through thevalve and into pipes 17 17, and the fluid in the cylinders and pipes 14 14 exhausts through the valve and exhaustport 22, moving the clamping memberslfrom clamping positions. When desired to lock the pressure-exerting fluid within the cylinders and pipes, the valve-lever is rotated to position 2Gb, which completely closes all ports. These valves l prefer to mount upon shaft 1, as indicated, and to admit the fluid .to them by means of an opening 23, formed longitudinally within and concentric with the axis of such shaft. Within this opening may be inserted pipe 24, connected with such valves and connected at its other end by a swiveljoint with a supply-pipe 26 from any convenient source. To more conveniently operate such valves, l pivotally secure to any convenient portion of the structures levers 27 27, one end thereof connected by a rod 28 with valve-levers 2O in any desired manner.

It will be understood that the unbalanced weight of a car upon the upper face of the rotating platform, as explained, will cause the platform and the structure secured thereto to rotate in the direction indicated by the arrow without the application of external niotive power. As an auxiliary means for rotating such structure when desired or for the purpose of accurately adjusting it at any desired position I form about the periphery of one or more of circular members 4 4 a series of gear-cogs 28 and provide one or more cogged pinions 29, journaled externally of and eccentrically to the circular member and adapted to engage cogs 28. Any convenient power may be utilized to operate the .pinion 29 and may be connected therewith in any desired manner. To control the velocity of rotation and to stop and lock the rotating structure at any desired point, l provide a brake adapted to engage therewith, and preferably in the form of a band or bands 30, extending entirely around one or more of the circular members, with the ends severally pivotally secured to the cross-head 31 of a lever 32, fulcrumed at 33 to any convenient stationary member. The lever 32 may be operated by hand but I prefer to connect the end 34 thereof by rod 35 with a piston working in a cylinder 36, adapted to throw lever 32 to the position 32 or any intermediate point, thereby tightening brake-band upon the circular member in the well-known manner of band-brakes. The piston inv cylinder 36 may be operated by the pressure-exerting fluid used in cylinders 12 and 16 or otherwise. To increase the resistance of the brake-band 30 against rotary displacement, l prefer to construct it in two approximately equal sections and at a point approximately opposite fulcrum 33 secure the other ends of the sections to any convenient stationary member, as indicated at 37, or in any desired manner.

To stop the car at the desired position and prevent longitudinal displacement, l mount horns 38 beside the rail, with a curved portion extending over and above such rail adapted to engage the tread of the carwheel. These horns l prefer to form integral with a plate pivotally secured in ahorizontal position beneath the rail and so connected with springs 39 as to be held normally with the horns above the rail, as described, but adapted to be rotatorially displaced by an oncoming car to allow the car to be pushed off by the dumping device.

While l have described as a preferred form of operating the clamping members the use of cylinders and pistons, it is obvious that IOO IlO

any other method of supplying sufficient pressure might be substituted-as, for instance, chains and winches or screw-pressure--and if such cylinders and pistons are used it is obvious that it is not necessary to use the particular form of four-way valve shown and described, as any convenient means for controlling the flow of the pressure-exerting medium would serve the same purpose. f

In an application for LettersPatent for an improvement in car-dumping apparatus, Serial No. 203,755, filed by ine on the 18th day of April, 1904, I have shown, described, and specifically claimed a rotary dumping device to turn a car entirely over and dump the contents, also means for retaining the car in position, aswell as various other-details shown and described in this application, and I do not, therefore, claim them herein.
